In my co-pending'application Serial No,

304,203,I have shown,described and claimed,

a flush valve having a main valve, an auxiliary valve carried by the main valve, a pivoted n lever carried by the main valeytor cpening the auxiliary valve, an actuating mechanism for swinging the vlever to openthe auxiliary4 valve, and a gravity acting trigger carried by L the lever to receive the thrust of the actuating mechanism whenopening the auxiliary valve, said trigger permitting the main valve tov close without unseat-ing the` auxiliary valve shouldl the actuating mechanism bein the path of the trigger during the closing ,movement ot the main valve. l. l

The use of a trigger requires that it-.be fulcrumed on the lever and also that the end of t the lever at the trigger' be spaced: inward.

fromthe actuating mechanism far enough topermit the trigger to drop into apcsition between the lever and the actuating mechanism so that the Vtrigger may yreceive `the thrust of the actuating mechanism 1 when starting'a flush through the valve.V` `Vlhile this arrangement is notobjectionable,jit is somewhat expensive to 'make and assemble,`

down movements. A gasket 12 is secured to the under side of the piston 7 about the guide 10 to seat against the upper end of the wall 5 when main valve 6is closed. The spaces between the webs 11 and the guide 10 provide the discharge passages for the valve when the `main valve 6 is open.

A tubular projection 13 extends upward from the piston 7 and is provided at its upper end with a gasket 141 which provides a seat for a relief on auxiliary 'valve 15. The valve" of the guide.

A by-pass `23 is. cored in the housing 1 on the 'intake side of the valve Aand opens -at its lower end into the intake connection 3 and at its upper end into the-chamber z8 abovethe piston v7. A timing pin 24 controls the flow o'fli'quids into chamber 8 from ithe intake 3.

The upper suraceof the piston V7 as lexpose'dto the water pressure in chamber 8 is greaterin area'than'the under surface ofthe piston `which is exposed to the Vwater pressure in the chamber 2 whenrthe valve '6 is closed. The result is, although'the pressure onropposite sides oi:l the piston will be the aiv saine'a's on the intakeside otthevalve, the 'valve' will'be-held closeda'gainstitsfseat by `reason of the greater area exposed to Ythe pressure `in chamber 8.

'For openingthe 'auxiliary valve 15 to relieve the ipressure inthe chamber 8 so that 'the main valve-"6 may be openedby the-pressure on 'its under side, the following actuat- `in'g'mechanism is provided.

A tubular Vboss 25 is cast integralwith the housing 1 Adirectly opposite the intake 'connectiori 3 and in substantial axial alignment therewith as indicated by the center line a in Fig. 1. Fitted in the boss 25 is a guide member 26 which has its peripheral liange 27 clamped against the outer end ofthe boss by hollow nut 28. j

Sli'dably mounted in the guide 26 is a plunger`29 having its head 3() in the nut 28 and held against the head ofthe handle 31 'b'y acoiled spring 32. Thevhead of "the handle 31 is mounted in the nut 28 andby reason 'ofthe enlargedopening 33 inlthenut, the handle may be oscillated in any direction `toinove the plunger 29 inward.

-Mounted on the lower arm 341ofithelever 2O isa gravity'-actingrmemberiin the lform of a sleeve 35 having a sliding lit on said arm. rlh'e latter terminates short of the plunger 29 so that the sleeve 35 may-extend below the arm 34L to be in the path of inward movement of the plunger and receive the thrust thereof when swinging the lever 2() to open the auxiliary valve 15. The arm 311 carries a stop v36 to engage a shoulder 37 on .thesleeve 35 to prevent the sleeve from dropping oii the end of the arm.

Asshown inthe drawings, the stop 35 is in the .form of a screw threaded into the lower end of the arm and having its head slightly ylarger y.than the arm so as to project beyond the sides of the same. The bore of the sleeve '35 isen'larged at the lower. end of the sleeve to lit Iabout ath-e head of the screw and provide the shoulder37. v Y

To o'penfthe auxiliary valve 15 .tostart vthe flushing operationgthe plunger 29 is moved inward by oscillating the handle 31. VThis thrusts theinner end of the `plunger against the sleeve 35 and swin gs the 'lower arm of the lever 20 inward. This swings the upper arm 19:01: the vlever upward, and the auxiliaryV valve 15 is unseated. This relieves the pressure in the chamber8 through the main valve 6 and the piston 7 moves upward carrying the lever 2O therewith. This carries the sleeve 35 above vand out yont contactwith the plunger '297 andtheauxiliary valvef15 closes 'by the action of the spring 18. The sleeve 35 is so proportioned that it remains in abutting` contact'with the .inner end of the plunger for substantially the 'full opening movement of the :main valve 6, lthereby insuring a full opening of the main valve before the ksleeve is rel-eased from the plunger to allow theauxiliary valve to close. Pressure-builds up in the chamber iS-threugh the byfpass23 asseon as the relief valveg15 closes and the main v-valvef closes to cut ol'lifthe flow from`3 toe.

`Should the handle 31 be held in valveopen- Eing position during 'the descent of the main valve 6, the plunger 29 will -be inthe/path j o'fdownwa-rd movement of the sleeve 35. vThe ylatter, however,` on rcontact with -theplunger 29 will 'slide upward onthe leverarm 3i and prevent -unseatingo the auxiliary valve 15, as shown in Fig. 2. "When thehandle -31 isV released` the plunger 29 will beretractedby VAspring 32, reeingthe sleeve 535and Aallow- -lnain valve 6.

With the partsy so'located, the height 0f the valve assembly is considerably reduced,

The details of structure and arrangement of parts shown and described may be vari-l ously changed and modied Without `departing from the tion.
